FLOOD-GATE.

I'E'ECIPIGATIOIT forming part of Letters Patent No. 340,293, dated April20,1886.

Application filed January .16, 1886. Serial No. 189,.571'. (No model.)

To ctZZ whom it may concern:

Be it known that I, JOHN DATLEY, of Van W'ert, in the county of Van\Vert aacl'State of Ohio, have invented a new and Improved Flood-Gate,of which the following is a full,

clear, and exact description.

My invention relates to the construction of a gate which will preventanimals from pass-' ing up or down the stream, but which is so arrangedthat when struck by any heavy debris carried by the stream it will swingupon its connections and be automatically raised to a position such aswill allow the debris to pass on down the stream, the said gate being soI 5 mounted that it may be raised quite a distance which similar lettersof reference indicate corresponding parts in all the figures.

Figure 1 is a side view of the gate and connections,certain parts beingshown in section to disclose the construction, and the gate be- Fig. 2is a cross-sectional view of the gate, and Fig. '3 illustrates theposition of the gate when raised above the stream.

In building such a gate as is illustrated in the drawings above referredto,I place two posts,

A A, in the position indicated--that is, one post upon each bank of thestream across These posts are each recessed at their upper ends,as shown3 at a, and in the recesses so formed I mount sheaves b b, over whichsheaves I carry ropes c c, fixed to the upper part of the gate B, saidgate being formed to the approximate contour of the bank of the stream.

5 as shown at g, and formed with an upper central aperture, h, throughwhich the ropes c are passed, so that they may be carried down toconnect with the plates d, which are mounted in the slots 9. From thisconstruction it will be understood that when the springs e are free toact they will force the plates (1 downward to the position shown in Fig.3, and thus raise The other ends 40 of the ropes c are fixed to platesd, which are the gate above the surface of the stream; but in order thatthe gate may be held in its lowered position,as shown in Fig. 1, Iprovide each post with a stop, 0, said stops being fixed to the innerface of the post. These stops 0 are 1-shaped, having a horizontal and aperpendicular bearing-surface, the perpendicular bearing-surface beingupon the downwardlyextending lug 7:, which is toward the upstream sideof the post. i

In order that the gate may be depressed, to be brought into engagementwith the stops G, I connect a lever, D, with one of the side posts, A orA, said lever being preferably mounted in a stirrup-loop, Z, carried byan arm, E, that is fixed to the supporting-post. The extending end ofthe lever D is loosely connected to the upper bar of the gate 13, sothat by lifting the shore-arm of the lever the gate will be carried downbelow the horizontal face of the stop, and then if said arm of the leveris carried downstream the gate will be carried upstream and beneath thestops, being brought against the lugs k, which define .the position ofthe upper bar of the gate. The downstream corners of the gate are cutaway or rounded ofi, as shown at t i, so that as the lower part of thegate is carried forward in the direction of the arrows in Fig. 2 thegate will slightly rock upon the stops, but when the force of thecurrent subsides will return to its normal vertical position. If anyheavy debris should be thrown against the upstream face of the gate,itwould be carried free of the stops 0, and the springs 6 wouldimmediately act to draw the gate to the position shown in Fig. 3, thuspreventing it from receiving serious injury.

One very material advantage arising from my improved form of gateisthatas the winter months approach the gate may be freed from engagementwith the stops 0 and raised above the surfaceof the stream,where it maybe left during the winter months, and thus be unexposed to thedangerarising from the breaking up of the stream in the spring.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. The combination, in aflood-gate, of the posts provided with stops, a gate suspended from theposts and resting against the under faces of said stops, and means forraising the I gate when forced away from the stops, substantially as setforth.

2. The combination,with the posts provided with stops on their adjacentfaces, the stops each having a horizontal and a perpendicularbearing-surface, of a gate suspended from the posts,with its upstreamcorners resting within the angles of the stops, and means for raisingthe gate when forced away from the stops, substantially as set forth.

3. The combination,with the posts provided with '1-shaped stops facingdownstream, of a gate hearing at its corners in the angles of the stops,a lever pivoted to one post and to the central part of the gate, anddevices for raising the gate when forced away from the stops,substantially as set forth.

4. The combination of the posts provided with sheaves at their upperends and shaped stops on their adjacent faces, of the gate bearing atits uppercorners in the angles of the stops, ropes connected to the gateand passed over the sheaves, and springs acting on the opposite ends ofthe cords to pull them down, substantially as set forth. 4

5. The combination, with the posts having sheaves on their upper endsand stops on their inner adjacent faces, of a gate resting at the endsof its upper edge against said stops, ropes connected to said ends andpassed over the sheaves, slotted standards on the outer faces of theposts, between which the free ends of the ropes pass, plates on the endsof the ropes within the slots, and springs surrounding said standardsand bearing on the plates to force the ropes down, and thereby raise thegate when forced from the stops,substantially as set forth.
